# What are legacy integrations {% hint style="warning" %} Please note that the Postman Team will not be actively supporting these integrations. These integrations were created to assist agencies during the transition of the gov.sg sender id mandate.\ \ All agencies should migrate these legacy systems to use Postman to send SMSes via our UI or APIs. {% endhint %} The Postman Team created the following integrations to support agencies with legacy systems: * **SFTP** - agencies who had legacy systems which were unable to make direct API calls * **Postman NRIC** - agencies who were dependent on Singpass Notify feature Given that the team is no longer onboarding any new users and these integrations are meant to be decommissioned, the guides for this section will not be available. Should you require any assistance please reference this page [FAQs (SFTP, Postman NRIC)](/legacy-integrations/faqs-sftp-postman-nric.md) as the team will not be providing active support. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
